While the C standard technically allows for the compiler to translate
pointer = 0 or pointer = NULL into something other than filling the
pointer address with 0 bytes, the rest of the Xlib code already assumes
that calloc initializes any pointers in the struct to NULL, and there
are no known systems supported by X.Org where this is not true.

Casts were annoying gcc by dropping constness when changing types,
when routines simply either copy data into the request buffer or
send it directly to the X server, and never modify the input.

This provides a simplified version of the SetReqLen macro when using clang for
static analysis. Prior to this change, we would see many Idempotent operation
warnings inside this macro due to the common case of calling with arg2 and
arg3 being the same variable. This has no effect on code produced during
compilation, but it silences a number of false positives in static analysis.

IsModifierKey, defined in include/X11/Xutil.h, is a macro determining,
which keys are regarded as modifiers. The constants ISO_Level5_Shift,
ISO_Level5_Latch and ISO_Level5_Lock where excluded previously, leaving
some Neo2 modifiers functionless in combination with compose.
This patch adjusts the range to include the correct, full range of
modifier constants.

Unfortunately the other return values for *status don't fit into the
error (which appears to indicate some internal error or running out of
memory). The other valid status codes are XBufferOverflow,
XLookupNone, XLookupChars, XLookupKeySym, and XLookupBoth. Each of
these has a specific meaning attached.
